The goal of the Holzinger Group is to design and develop algorithms which can learn from data and improve with experience over time. However, the application of such automatic machine learning (aML) approaches in the complex health domain seems elusive in the near future, and a good example are Gaussian processes, where aML (e.g. standard kernel machines) struggle on function extrapolation problems which are trivial for human learners.
Consequently, interactive ML-approaches, by integrating a human-into-the-loop and making use of human cognitive abilities, seem to be a promising approach. iML-approaches can be of particular interest to solve problems in health informatics, where we are lacking big data sets, deal with complex data and/or rare events, where traditional learning algorithms suffer due to insufficient training samples.
Here the “doctor-in-the-loop” can help, where human expertise and long-term experience can assist in solving problems which otherwise would remain NP-hard. Successful ML for health informatics requires a deep understanding of the data ecosystem and a concerted effort of 7 research topics: 1) data integration, 2) learning algorithms, 3) graphs, 4) topology, 5) entropy, 6) visualization, and 7) privacy, data protection, safety and security.
Consequently, Andreas and his Group work on a synergistic combination of methodologies of two areas that offer ideal conditions towards unraveling such problems: Human-Computer Interaction (HCI) and Knowledge Discovery/Data Mining (KDD), with the goal of supporting human intelligence with machine learning to discover novel, previously unknown insights into data. Andreas is passionate on extending advanced methods including time (e.g. information entropy) and space (e.g. computational topology), along with user-centered software engineering to create interactive algorithms and tools for data science. Andreas is founder of the Expert Network HCI-KDD and Assoc. Editor of Knowledge and Information Systems (KAIS) and Brain Informatics (BRIN), and member of IFIP WG 12.9 Computational Intelligence.
